This is the fixed part of the DWH offer: these datasets are typically pre-defined large datasets, covering the needs of the Copernicus services and other activities requesting Earth Observation data, like Union financed research projects and the activities of Union agencies (EEA, EMSA, SatCen, etc.). CORE datasets are characterised by fixed tasking, systematic or not, data processing and delivery timeliness parameters defined a priori.

Status of the coverage achievement for each dataset can be monitored via the CORE dataset status document updated monthly on the Data Provision Status section of the portal.

Dataset Composition

This dataset was built using instruments from: Mission Group 2: Optical high resolution multispectral.

Image 2009: majority of IRS-P6/ResourceSat-1 with gap filling and Atlantic Islands Azores/Canaries and French DOM areas by SPOT-4/-5

Image 2006: composed of both IRS-P6/ResourceSat-1 and SPOT-4/-5

HR2 (23.5m and 20m not orthorectified//20m and 25m orthorectified), SWIR, VNIR. Cloud coverage should be less than 5% per country, products are (mostly):

Without haze

Snow coverage: only glaciers and perennial snow

Sun elevation angle higher than 23 degree

Instrument incidence angle has to be less than 20 degree

15 products over Iceland belonging to the Image2006 dataset were discovered to be not correct and have been re-processed and re-distributed by Metria: the 15 orthorectified SPOT-4 products in National projection have been archived in the folder /IS/Coverage_1/National/RecorrectedlData of the Image2006 ESA Rolling Archive repository.
